The extension of the Blue metro line towards Anjou, on the Island of Montreal, was decided to improve access to this eastern part of the island, and to provide a facilitated correspondence with the new Pie-IX rapid bus service, along with providing a better service to Anjou’s borough businesses and companies. Five metro stations will be added east of the actual Saint-Michel station, which will also be modified. Furthermore, over 5.5 km of underground infrastructure will be built, along Jean-Talon Street.

Those infrastructure include:

• Kiosks, emergency exist, bus stops and bus terminals, with Park-and-Rides;
• Surface installations around the metro stations, including: road network, urban furniture, walkways, bike areas, waiting areas and taxis, kiss and rides, and parking for users and emergency vehicles;
• Underground infrastructure, including: platforms, mezzanines, maintenance and warehousing areas, ventilation shafts, horizontal and vertical circulation areas, pumping stations, rectifier rooms, signalling rooms, secondary distribution areas, personnel rooms and technical hallways, cables and ducts galleries, etc.
